I have a 486-66 with a Diamond Stealth 32 graphics card running wfw3.11. 
The problem is that periodically it either locks up or an application 
crashes usually saying "xyz caused an error in stlth32.drv". When it 
locks up pressing Ctrl-Alt-Del gets the "system busy or unstable" 
message. Pressing enter usually gets the "xyz caused an error in 
stlth32.drv" message, the application closes and the system apparently 
carries on as though nothing had happened. Restarting the application 
straight away, rather than rebooting, doesn't seem to make it any more 
likely to cause further problems.

I upgraded my motherboard a few months back (from a UC4914-G, made by 
who knows who, fitted with an Intel 486SX 33 to a PAT48PG, made by TMC 
whoever they are, fitted with an IBM 486DX2 66. I'm pretty sure this was 
when the problem started.

I have also found that the problem goes away if I use the standard 
windows SVGA drivers, so far as I know I have the latest Diamond driver. 
I tried a Tseng driver which I downloaded, this was as bad as the 
Diamond one.

This all leads me to thing that it must be either a faulty mother board 
or an incorrect BIOS setup. I have noticed that on this M/B two of the
VL 
slots are labelled "Master/Slave" and the other "Slave" I have a QD6580 
VL IDE card, so does it matter which is in which slot. The only thing 
along these lines that I could find in the Stealth manual was that 
"video shadowing" should be turned off in the BIOS setup, I turned off 
"video BIOS shadowing" (is this the same) but it made no difference.

Can anybody out there shed any light on this?
